IMPROVEMENT IN CHAIRS.

Specification forming part of Letters Patent No. 124,281, dated March 5, 1872.

To all whom it may concern:

Be it known that I, GEORGE W. Monsrnrr, of New York, in the county and State of New York, have invented certain Improvements in Chairs, of which the following is a specification:

The nature of my invention consists in the arrangements of levers connecting the upper and lower part of a chair to enable the seat to be raised or lowered, whereby a square or tour-legged chair or a double-seated pianochair can bemade without any suspended screw in the central part.

1n the accompanying drawing, Figure I represents a cross-section of a chair embodying my invention. Fig. II represents the same view with the seat raised upward. Fig. III shows a longitudinal section of the same; and Fig. IV is a plan with the seat removed.

B is the lower frame, having at each corner legs L attached. cushion or seat attached. 0 (J are levers crossing each other and attached through the pins to d to the upper and lower frames A and B, capable of turning on said pins [1. The other ends, '12, of said levers O 0 work in longitudinal slots m an arranged in the upper frame A and in the lower frame B. To the center of these levers O C a segment, D, is attached, provided on one side with teeth a, into which pawls w fit, acted upon by suitable springs 17. (See Fig. IV.) By this arrangement the upper seat A is the top frame with the A requires to be raised or lowered, and said pa-wls w are moved back again or forced into the teeth a: by the action of their springs o.

By this arrangement a square, oval, or any other desired-shape chair can be made with-.

out the necessary fixings required where a central screw is used for raising or lowering the seat; and at the same time a double-seated chair can be divided in two parts, where each part or seat can be raised or lowered independent of the other part or seat.

hat I claim as my invention, and desire to secure by Letters Patent, is-- The arrangement of the levers G (J, segments D, pawls w w, in connection with the lever 2, when combined with the upper and lower part of achair, substantially as and for the purpose hereinbefore set forth.
